of the invention, such as will enable others skilled in the art to which and use' the same. r

This invention relates to means for carbureting air by mixingiit with gasolene or other hydrocarbon fluid, and its object is to providea compact and eflicient device for the pur .ose.

T e invention consists in the construction hereinafter described and pointed out.

In the accom anying drawings, formin part of the speci it pertains to make cation, Figure 1 is a central ongitudinal section. Fig. 2 is a section of an air-valve or damper. Fig. 3 is a bottom view of said damper. Fig. 4 is an elevation of another form of the device, and Fig. 5 a central longitudinal-section thereof.

Numeral 1 indicates the circumferential casing or body of the device; 2, a gasolenesupply tube; 3, air-inlets; 4, an air-distributer; 6, a fluid-mixing chamber, and 7 a-conduit leading to an explosion-chamber. (Not shown.) The perforated part 4, such as customarily used in lanterns and the like and styled "airdistributers, divides or distributes theair as it enters the space surrounding the fuel-distributing ports in the on or part to be described both above and be ow said latter ports, with the effect to promote the mingling of the fluids.

The supply of gasolene or other fluid fuel is regulable by a needle-valve 8 and a cupvalve 9, the latter having a'face 10, of leather or other soft material. This cup or part 9 is a distributer and preferably distributes fuel in a plane transverse to the 'axis of. the needle-valve and in a proximately the middle of an air-receiving ciamberh Gasolene passes through fuel-distributing ports 11 situated, by preference, in the sides of'the valve 9, as indicated. Air entering orts 3 passes through the numerousdistri uting-perforations in the conical distributer 4, above which these fluids arepartially mingled, passl ing thence between the cup-valve and the diaphragm 12, fixed to casing 1, and throu h the 0 ening 13 in said diaphragm into the cham er 6, where the air and gasolene are further mixed preparatory to an escape Specification of Letters Patent.

, -I through the circumferential opening 1.7 in the diaphragm 14, which is normally closed by" a valve 15 under the influence of a spring 16.

The valve 15 comprises a part of leather or other flexible material held between two plates 16*, the lower one of which is movable into opening 17. This valve has a tubular stem 18, movable in a hollow post 19, fixed to the casing-cap 20, having a flange 21 with screwthread connection with the casing.

through valve 15 and its stem 18 and held The cup-sha ed body of valve 15 has a diameter a litt e less than that of opening 17, substantially as indicated. The leather piece 10 is fixed in the bottom of the cup and above the gasolene-exit ports 11. Said cup fits over the casing 24 of the needle-valve, and its softface normally closes or nearly closes the port 25, receiving at its inlet end the point of the needle-valve. The casing 24 may be integral with the tube 26, fixed to the base 27 of the casing 1, as by screw-threads at 28.

29 indicates a thimble of a stufling-box, which has a screw-thread connection with the screw of the needle-valve. The stem of the needle-valve has fixed thereto a pinion 30, meshing with a pinion 31, rotating on a stud 32.

33 denotes a circumferential damper having orts 34 adapted to register with ports 3 in ,t e casing 1. It has a flange 35 approximately semicircular, provided with teeth and constituting a rack to drive the pinions.

36 is an operating-handle, and 37 is a cotter to support the damper from the needlevalve stem.

The construction is such that rotating the dam er to open the air-ports also opens the needYe-valve during a partial rotation of the damper or until the rack 35 escapes from inion 31, whereupon the air-ports may be further opened without disturbing the needlevalve.

The construction thus far described is to secureadditional advantages in manner illustrated in Figs 4 and 5, in which a flat or iston valve 38, faced with soft material and cooperating with a cup 39, cast with a valve-casing 40, is employed. Said casing communicates with sediment-receptacle 41 by means of a sediment-conveying tube 42, as clearly shown. 43 denotes the stufiing- The cup-valve 9 has a stem 22 extending therein in a regulable manner by a nut'23.

simplified in certain details and also modified box of needle-valve 8 Said valve is regulable by a nut 14, slidably keyed to the valvestem at 45, the stem. having a screwthread connection with the casing If If independ ent regulation of either the needle-valve or damper is desired, the nut 44 can be disen gaged from the pinion by sliding the nut on. the valve-stem, the spring being thereby oompressed,if it has not previously been removed. The nut being thus disengaged from the pinion can be manipulated to adjust the valve, and thedamper can be independently adjusted. Said nut 44 is also adapted to regulate the circumferential damper 33 having air-admission ports comm.u meat-mg with'correspondmg ports of the cas= ing, and this regulation may be either snnul-- mdependent of the valve It is eflected by a pin 46, adapttaneous with or regulation.

The damper-is supported on a ledge or flange 52 on the casing.- The flat or piston valve combined with the cup or cylinder integral with the valve-body acts efficiently, and particularly this construction avoids overflow of gasolene.

To prevent the burcter,it is provided with a jacket 53, having an opening 5 l whereby it communicates with the usual cooling-coil of an engine or with. any suitable source of water-supply. Such protection is of special importance in a carbureter necessarily exposed in use to low teji npera turcs.

A spring The construction whereby dirt, water, andother residuum is separated from gasolene is of great practical advantage. Obviously the particular form of the sediment holder or receptacle is not material, and more mechanical variations not substantially affecting the operation. of

ierein.
